The other end of the connecting plate 332 is vertically connected to the middle part of the outer side of one of the push rods 333.

[0038] like Fig.10 As shown, four transverse members 34 are provided and are respectively installed corresponding to a support ear 315. The transverse member 34 includes a transverse rod 341, a first spring 342, a mounting plate 343, a limiting plate 344, and a first roller 345. The transverse rod 341 is penetrated by the support ear 315, the first spring 342 is penetrated by the transverse rod 341, the mounting plate 343 is L-shaped, and a side of the vertical portion of the mounting plate 343 facing the support ear 315 is connected to an end of the transverse rod 341 facing the boss 311, the limiting plate 344 is provided at the outer end of the transverse rod 341, and one end of the first spring 342 abuts against a side of the limiting plate 344 facing the support ear 315, and the other end abuts against the support ear 315, and the first roller 345 is installed on a side of the limiting plate 344 away from the support ear 315, as shown in FIG. Figure 3 As shown, the first roller 345 abuts against the inner side surface of the corresponding push rod 333 to reduce the friction between the limit plate 344 and the push rod 333. The cross-section of the push rod 333 is preferably a rectangular structure so that the force on the first roller 345 is uniform, so that the transverse rod 341 has better stability when moving toward the boss 311.

[0039] Each transverse moving member 34 is provided with a corresponding vertical moving member 35. Fig.10As shown, the vertical moving member 35 includes a positioning plate 351, a vertical rod 352, a second spring 353, a limiting seat 354, an inclined surface 355, and a second roller 356. The width of the positioning plate 351 is consistent with the width of the groove 313. The vertical rod 352 is vertically penetrated through the horizontal portion of the mounting plate 343. The upper end of the vertical rod 352 is connected to the lower end of the positioning plate 351. The middle part of the vertical rod 352 passes through the horizontal portion of the mounting plate 343 and then slides with the guide groove 314. The lower end of the vertical rod 352 passes through the guide groove 314 and extends downward. The limiting seat 354 is arranged at the lower end of the vertical rod 352, the second spring 353 is sleeved on the vertical rod 352, the upper end of the second spring 353 abuts against the bottom surface of the base 31, and the lower end abuts against the upper end of the limit seat 354, the inclined surface 355 is arranged at the lower end of the limit seat 354 facing the conical platform 321, the inclination of the inclined surface 355 is consistent with the generatrix inclination of the conical seat 321, and the second roller 356 is arranged in an array along the inclination direction of the inclined surface 355, that is, the axial direction of the second roller 356 is arranged perpendicular to the length of the vertical rod 352, as shown in FIG. Figure 4-Figure 5 As shown, the second roller 356 is in rolling contact with the outer wall of the conical seat 321 .

[0040] The specific usage process is as follows: When the ton bag 1 is hung on the hook 143, the lifting rod 12 is moved along the length direction of the beam 11, and the first conveying roller 21 is started at the same time, so that a tray 2 at the front end of the first conveying roller 21 in the conveying direction enters above the boss 311 in the accommodating cavity 23. The movement can be achieved by arranging a chain transmission structure above the beam 11 to drive the lifting rod 12 to move along the length direction of the beam 11, or by a synchronous belt transmission structure.

[0041] When the ton bag 1 follows the lifting rod 12 to move to the upper end of the accommodating chamber 23, the lifting rod 12 is moved vertically downward. When the lower end of the ton bag 1 drops to the top close to the side beam 22, Figure 11-Figure 12As shown, the second cylinder 331 is started, so that the second cylinder 331 drives the connecting plate 332 to move, thereby the connecting plate 332 drives the push rod 333 to move, so that the push rod 333 approaches the direction of the base 31, thereby driving the rotating plates 334 at both ends to rotate, so that each push rod 333 synchronously approaches the corresponding side of the base 31, so that the push rod 333 acts on the corresponding first roller 345, so that the corresponding limit plate 344 pushes the corresponding transverse rod 341 to move toward the boss direction, so that the mounting plate 343 drives the vertical rod 352 to move along the guide groove 314 toward the direction of the groove 313, so that the vertical rod 352 drives the limit seat 354 to move toward the upper end of the conical seat 321, so that the positioning plate 351 extends upward along the height direction of the groove 313. When one side of the positioning plate 351 facing the groove 313 contacts the concave part of the groove 313, the upper end of the positioning plate 351 contacts the outer side of the bottom of the ton bag 1, and the middle part of the positioning plate 351 contacts the outer edge of the pallet 2, so that the center of the pallet 2 corresponds to the center of the ton bag 1, and finally the lifting rod 12 is vertically upward to place the ton bag 1 on the pallet 2.

[0042] Start the telescopic rod 142 to move the hook 143 vertically upward, thereby disengaging from the hanging ear on the ton bag 1. When the hook 143 is disengaged from the hanging ear, start the first cylinder 141 to make the telescopic rod 142 drive the hook 143 to move away from the ton bag 1. Finally, start the lifting rod 12 to rise, so that the lifting assembly 10 is away from the ton bag 1 and prepare for lifting the next ton bag 1.

[0043] When the ton bag 1 is placed on the pallet 2, the second cylinder 331 is activated to drive the connecting plate 332 to move in the reverse direction until the ton bag 1 is placed on the pallet 2. Fig.13 When the positioning plate 351 moves downward under the action of the second spring 353, the traverse rod 341 moves away from the groove 313 under the action of the first spring 342, and the Fig.14 The status shown is reset.

[0044] Finally, start the lifting platform 32 so that the lifting platform 32 extends vertically upward from the accommodating hole 312, and makes the top surface height of the second conveying roller 322 equal to or higher than the top surface height of the first conveying roller 21, and start the first conveying roller 21 and the second conveying roller 322 at the same time, so that the pallet 2 carrying the ton bag 1 is conveyed to the first conveying roller 21, and output to the next workstation under the action of the first conveying roller 21.

[0045] Specifically, Figure 2 , Figure 5 As shown, the height of the boss 311 is lower than the top surface of the first conveying roller 21 , so that when the tray 2 moves to above the boss 311 , it moves out of the range of the accommodating cavity 23 under the action of inertia.

[0046] Specifically, Fig.10 As shown, in order to prevent the vertical rod 352 from rotating when moving upward or downward, a square hole is penetrated through the horizontal portion of the mounting plate 343, and the vertical rod 352 is inserted into the square hole.

[0047] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
